Los Blancos are understood to be long-term admirers of the Belgian and have previously been linked with a move for the player, who has been at Stamford Bridge since moving from Lille in 2012.

On Monday it was reported that Hazard is dragging his heels over signing new terms with the Blues in the hope that the Spanish giants might make a move, and according to Diario Gol, manager Zinedine Zidane has been in touch with the 26-year-old over the last week.
